Product Overview
The 25Gbps-SFP28-SMF-1310nm-10km-industry module (Huawei part number 02312PDL, model SFP28-25G-1310nm-10km-SM) implements 25.78125 Gbit/s 25GBASE-LR transmission at 1310 nm over singlemode fiber with a documented 10 km target distance, and is listed against IEEE 802.3cc 25GBASE-LR with 10GBASE-LR support for rate adaptation.
Huawei documents a Tx power range of -7 to +2 dBm for this module and markets it as an industrial-grade part, making it suitable for outside-plant cabinets and unconditioned sites where the standard commercial range would be marginal. It uses the standard SFP28 footprint with an LC duplex connector.
Typical applications include 25G spine-leaf and campus uplinks between Huawei switches over dark fiber, 5G fronthaul/backhaul cellsite aggregation links, and 25G links to routers at metro nodes up to 10 km away.
- 25GBASE-LR 25.78125 Gbit/s transmission over 1310 nm SMF (IEEE 802.3cc)
- 10 km reach on singlemode fiber; also supports 10GBASE-LR
- Tx power -7 to +2 dBm per Huawei official documentation
- Industrial-grade temperature rating for unconditioned sites
- Huawei part number 02312PDL for precise reorder matching
